6 Claims.

In the splicing of electrical conductors, more particularly strands ofcables such for instance as those used in telephone and telegraphservice, it is the present common practice to bare short sections of thewires, twist them together, cover the twisted and adjacent exposedportions with an insulating paper tube, preliminarily slipped over theend of the strand, and then cover the completed splice with meltedparamn. This operation is an exceedingly tedious one and, so far as Iknow, no machinery, capable of rapid operation, has been produced forperforming such operations except in connection with the splicing of thestrands of large cables, such mechanism be ing of such size andcharacter that it cannot be readily generally utilized.

The Aobject of my present invention'is to produce an article ofmanufacture which can be readily and quickly applied to effectivelyelectrically connect two wires without the necessity of preliminarilytwisting such wires together, the article being ci such character as tobe very readily and quickly applicable 'to the wires no matter wherethey may be located.

The accompanying drawing illustrates in= vention.

Fig. 'Z a plan, slightly enlarged, of the blank from which the core ofmy device is produced.

In the drawing 16 indicates a sheet metal blank, of suitable size,thickness and material, conveniently sheet copper, medially slotted twoslots 11, l1 longitudinally extending between the two fold lines 12, 12and having a width slightly greater than the diameter ot the wires to bespliced. The blank thus formed is iolded on the medial line 13; the endsthen are oppositely rea folded on the lines 12; and the tips refoldedto1 ward each other and inwardly on the lines li-lll.

This folding produces end ngers 16, 16,` and middle linger .17, whichare then laterally displaced, and the flanking cover sections i8, 18,each of which is provided with an inturned lip 19. The fingers 16 and 17are preferably op- 60 positely slightly bowed, as clearly shown in Figf2. Covering the metal core so formed is a sheet ot insulating material20, the side edges of which are clamped between the lips 19 and adjacentcover sections 18, as indicated at 21 in Fig. 2. Width of material 20 ispreferably somewhat greater than the width of the core, so that the endsof the insulation will extend beyond the core, as indicated in Fig. 3,so as to overlie the adjacent undisturbed insulation 22 of the` wires23.

The insulation may conveniently be fabric or tough paper preliminarilysoaked in paraffin or other insulating material if desired.

tongues i6 and 17, and forming a thoroughly efficient electricalconnection and a firm interlocking of the wires.

The time consumed in making splices by means of my device is very muchless than the time required by present methods and the electricalconnection is thoroughly eiiicient. Vv'hen the splices have eeencompleted the entire group may be impregnated with parafn in the usualmanner.

l claim as rny invention:

l. As an article of manufacture a wire splice formed of a metal sheetlongitudinally slotted and folded upon a medial line and refolded upon apair of separated flanking lines to form stag-u gered medial tongues andflanking cover sec= tions.

'2.' it splice of the character specified in claim l. havinganinsula'ting cover extending thereover and means on said core rmlyclamping said cover to said core.

3. las an article oi manufacture a wire splice and an insulating coverembracing said core with edges thereof clamped between the coversections and lips of the core.

4. As a new article of manufacture, a splice clip comprising a metalelement formed to provide a socket of generally V-shaped cross sectionadapted to receive bared portions of a pair of conductors, and membersdisposed in the V socket of said element and adapted, upon collapse ofthe walls of said socket, to crimp said wire portions.

5. A splice clip comprising a metallic element formed to provide aV-shaped socket, and adapted to receive portions of a pair ofconductors, a pair of tongues longitudinally spaced from each other andprojecting upwardly in the socket of said element, the major portions ofsaid tongues lying on one side of the median line of said socket, and atongue disposed longitudinally between said rst-mentioned tongues andwith its major portion lying on the opposite side of said median line,whereby, when said clip is collapsed. said pair of tongues and saidsingle tongue will grip oppomte sides oi a wire disposed therebetweenand crimp said wire.

6. A wire splice comprising' a paix' of wires having portions disposedin close parallelism, and a clip firmly grasping said wires, said clipcomprising a pair oi.' side members, a pair of abutments contacting theinner face o! one of said side members and spaced from each other, andan abutment contacting the inner face oi the other oi said side membersand registering with the space between said mst-mentioned abutm'ents,said side members and said abutments gripping said wire portions, andsaid side members being separated from each other by a distanceequivalent to the diameter of one ot said' wire portions plus thethickness of one of said abutments.
